Kosaka always had a 50/50 record and he was ranked only #14 in the world when he fought Fedor the first time and #12 when they fought the 2nd time. And he’s an impressive 5’11 tall 220 pound “heavyweight”. Lol. The fact he was ranked even that high, just shows how shitty was the division back then.
And do champions deserve praise for beating #12 guy in the world? Imagine Ngannou putting up a 3 win streak next, against guys like Tybura, Augusto Sakai and Oleynik. Nobody would give a shit! Somehow Fedor is considered a god for such an incredible achievements. His win streak only lasted so long because he had 3-4 cans between each credible opponent.
Koshaka was former Top 5 fighter at the end of 90's, and a big name in MMA, man who significantly contrubuted to some elememts of its development. Why whould fighting him in 2000 be different from UFC upcoming stars fighting former big names like JDS, Cain, Arlovski, Overeem etc, and UFC fanboys hyping that kind of adding former big names on resume as big thing?
Fighters did not protect scores back then, and took all kinds of opponents, in different rules without months of preparation, different from nowadays modern consumeristic mentality of score protecting, fighting once per year and 15 times in life, and cherry picking opponents, whining about rankings.
Koshaka had very impressive career with many good wins, including win over Fedor, and draw vs Minotauro, wins vs Volk Han, Maurice Smith, Pete Williams, Gilbery Yvel, Ron Waterman, Mihail Ilyukin, Kimo Leopolodo, Morais, Sperry.
You are beeing a hypocrate, because you would include someone wha had few big wins in UFC as big win for some UFC champion.
Also Ngannou could as easily loose to some lesser name fighters if he would take more fights and fight more often.
It is not true that only absolutely top fighters can beat top fighters, you can as easily lose to lesser name at HW (Imagine JDS taking fight against unknown and unranked Ngannou in 2015-16 for example, or unknown JDS beating Werdum), escpecially when you fight often, do not have half a year to rest and prepaire and study opponents, and when you don't really want to be in fight, and other guy is motivated and has nothing to lose.
Modern UFC 15-20 fight in career standard, and fighting once per year could as easily be fake picture, and it does not mean that you are unbeatable if you fought only small amount of different opponents.
